What is GEO

Generative Engine Optimization (GEO), sometimes called Answer Engine Optimization (AEO), is the practice of improving whether a brand, source, product, or entity is mentioned, cited, and accurately represented by AI answer systems such as ChatGPT, Perplexity, Gemini, Claude, Copilot, and Google AI Overviews. It overlaps with SEO, but shifts measurement from ranked pages to cited sources, answer inclusion, entity understanding, and share of voice inside generated responses. For a longer overview, read Generative engine optimization.
